FENCE-WIRE-BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 253,824, dated February 14, 1882. i

Application filed December 23, 187B.

To all whom 'it may concern:

Bennington. in the State of Vermont, haveinvented an Improvement in Fence-Wire-Barbing Machines, ot' which the following is a specilication.

This machine is for making what is knownstop-motion gearing. Fig. 5 shows thev S-` shaped barb; Fig. 6, the device for holding the fence-wires While the barb is being applied. Fig. 7 is an elevation of the drawing-rollers that move the wire-along. Fig. 8 is a section of the tubular'guide for the wire and the barh- Winder. Fig. 9 is an end view of the barbwinder ready to act on the wire. Fig. 1'() represents the winder with the barb completed. Fig. 1l represents the fence-wire with the barbs upon it, and Fig. l2 represents the winder with the barbs wound to a less extent than in Fig. 10.

The tubular guidej has a hole throughit that is adapted to pass the fencc-wiresfh through it side by side or parallel, such hole not being circular, but elliptical, so that the wires can pass through freely but ycannot be revolved in the hole. (See Figsr, 8, and 9.) The tubular guidej is held at one end in the stationary head a', Figs. 1 and 8, so that it cannot revolve, but itvmay slide endwise. Around this tubular guide j there is the tubular ba-rb- Winder K, having projecting ngers a at one end. This tubeK is supported in the`stationary heads b c on the bed A. There is a groove and key at b c, Fig. 8, that connects the tube K and guide j, so that they must move endwise together; but the tube K can be revolved around the guide j.

Motive power is applied to the wheel B and shaft K', and the same acts by the gearwheel G upon the wheel H to revolve the same periodically, there being aplain segmental Be it known that I, HENRY W. PUTNAM, of l portion and an arm, L', on G, and two concave segments and two st uds, U', on the wheel H,`-the whole forming a stop-gear that revolves 'thc'wheel'H half a turn for each revolution ot' the wheel G. The wheel H is upon a shaft that carries a imiter-gear, l, and revolves the wheel J, that sur; onnds Athe barb-winding tube K, and is connected thereto by a key or feather,

so that the tube K can be moved endwise 'as The barb-wire k passes through a guide, R,

beneath a spring, Q, that presses it upon a channel-piece, P', (see Fig. 6,) and there is a standing shear, T,and moving shear S, that cut ofi' the barb with a diagonal and shearing cut, and the shear S is connected to the stock M, 'that slides in the bed -block N on A, and the cam F on K gives motion through the rod L to this stock 1\l to shear oli' the barb-wire, and at the same time the pin or fork P/ on M gives end motion to the barb-Winder K, before described. The screw Q beneath the channelpiece P adjusts the latter so that the pointed end of the barb-wire is directed and it passes through between the fence-wires f and It when the shear S has been drawn back. It is to be understood that continuously-revolving friction'irollers or other devices are employed to time.

The jaws m form stops for the end ot' the barb-wire. (See Fig. 6.) These are on levers P and adjusted bythe screw S'. The end ot' the barb-wire as cut to form a point is stopped by these jaws m without the end of the barb being blunted 'b v contact with the metal. It will now be evident that, it the barb-winding cylinder K is revolved after the barb has been inserted through between the wires and cut 0E, the fingers a a, will carry thc barb-wire around Vthe wires f h, bending the same into the S-shaped barb, during which time the tubular guidej will hold the wiresfh in position. I, however, have also employed holding-jaws R at the ends of levers 0', to grasp project the barb-wire forward at the proper IOO the Wires f h and keep them firm while the levers O with a plate that slides upon the standard U and is moved by the lever M and cam E. By these means the jaws Rare opened and closed at the proper time.

rEhe wires f h, being fed from suitable reels,

. pass through the tubular guide j. The barbwire is run across at the end ot' tubular guide j between the wires f h, the barb cut on, then the winder K and guide-tube j are moved endwise to clear the ends of the barb, and the winderK is revolved, bending the barb into the S Shape, and the end movement brings the fingers a adjacent lo the jaws It', so that the linal finishing of the barb is between the end of K and said jaws R', and the barb is held rmly in position and kept in a plane at right angles to the wire.

The wiresfh maybe forced through themaehine by frictional l'eedin g devices acting upon the same before it enters the tubular guide j. I have, liowever, shown the feeding-rollers Y Y in pairs, operated upon by the gearing g z, Fig. 1, that receives motion from bevel-gears W A andshat't X', Fig. 7; and to move these periodicallythe ratchet-wheel G', pawl H', and connecting-rod J from the y-wheelB are employed. The movement ot' the feed-wheels Y should be arrested when the barbs are being applied to the wires f h, and when the feed takes place the barbs pass into the recesses s s on the wheels Y, and are not injured. It is to be understood thatthis feed movement takes place as the barb-Winder K and tubular guide li-are being carried back, and after the jaws It' have been opened to relieve the wires f h and to allow the barb to pass through.

The stop-lever E and pins o upon one of the feed-rollers Y are used to arrest the movement of the rollers Y during the barbing operation. lhe cam F', Fig. 7, on the shaft D', acts against n to raise this lever E when the feed is to tahe place and dr'op the lever E in the path of one of the pins o, so that the movement ot' Y is stopped at the right moment. rlhis cam F Iand shaft Dl are moved by the gears C D. The rollers Y are to be grooved so as to grasp the wiresfh, and the screws B adjust the lower bearings, t, Fig. 6, of the shafts ot' Y, and the screws C adjust the upper bearings ot' Y, so as to suit dillerent sizes of wire and to apply the proper pressure to the same. The wires f L, with the barbs upon them, pass these rollers in a parallel, or nearly parallel, condition; but as they leave the said rollers the twist is applied to the wires f h to twist them into the condition shown in Fig. 11, and for this purpose the winding-reel is revolved around one axis in line with the wire, and also upon its own axis, so as to wind up the wire upon the reel. I have shown in Fig.

,2. this reel and its actuating mechanism, and in Fig. 1 the twists as applied to the wires after they leave the rollers Y Y; but as .this

reel and twisting apparatus are similar to the devices shown in Figs. 9, 10, and 11 of my 65 patent dated February 27, 1877, No. 187,776, it is not necessary herein to describe the details of the construction or operation.

I do not herein claim the parts that are also shown, described, and claimed in my applica- 7o tion (lated November 13, 1879, and allowed January 10, 1880-viz., the jaws m, that form stops for the pointed end of the barbed wire; nor the combination, with the barb winding and cutting mechanism, ot' the jaws R' and 75 mechanism, and the barb supplying, cutting, 8o

and twisting mechanism.

I claim as my invention- 1. The non-rotating tubular guidej for the two longitudinal fence-wires, adapted to p'revent them from twisting around, and at the same time allowing them to be drawn through such tubular guide, in combination with a barbwinder surrounding such tubular guide and receiving a rotary movement, substantially as set forth. 9o

2. The non-rotating tubular guide for the two longitudinal fence-wires and the barb-windet' surrounding such tubular guide, in combination with mechanism for revolving the barbwinder and mechanism l'or moving the barb- 9fwiuder and guide endwise, substantially as set forth.

3. The combinalion, in a t'encewire-barbing machine, of mechanism for introducing the barb wire between two longitudinal wires, mechanism for twisting the barb-wire around the longitudinal wires, mechanism for feeding along the wires, and mechanism for twisting the longitudinal wires together, substantially as set forth.

4. A non-rotating guide and holder for the main fence-wires, adapted to permit their passage along it, and at the same time to preventthem from twisting around each other at their guidedportions, in combination with a barb- Winder surrounding such guide, and with means for imparting a rotary movement to the Winder, substantially as described and shown.

5. The combination, in a fence-Wire-barbing machine, of mechanism for feeding longitudinal wires through the machine, mechanism for introducing the barb between the longitudinal wires, and mechanism for twisting it around both said longitudinal wires, substantially as described. A
